Entity's Keys

Browse source 
You can now give the 'key' component to Entities.

A key will be generated automatically and stored in Entity.key.value.

You can then use this key to fetch the Entity from the World with World:getEntityByKey(key)

The keys are generated with a generator function that can be overriden.
